The aerobic oxidation of hydrocarbon is of great significance from the viewpoints of both fundamental and industry studies as it can transfer the petrochemical feedstock into valuable chemicals. In this work, we investigated the aerobic oxidation of cyclohexene over TiZrCo catalysts, in which 2-cyclohexen-1-one was pr…
An increase in global consumption has led to an exponential increase in industrial production activities which inevitably results in overwhelming remain of industrial waste. Consequently it has driven increasing attentions of research and development teams in various countries to propose and investigate novel methodol…
Duplex stainless steels are materials that present high corrosion resistance with high values of mechanical strength, therefore motivating their use in various components in the offshore industry. However, there are major challenges in the welding of these materials in terms of the productivity and quality of the join…
Employing first-principles calculations, we study the effect of an external electric field on the magnetic properties of a single Fe adatom and a Fe dimer hosted on a bilayer graphene surface grown on a ${\mathrm{SiO}}_{2}$ substrate. We find that an electric field perpendicular to the bilayer graphene modulates the c…
In the antiferromagnetic ground state, below TN ≃ 5.7 K, Ca2CoSi2O7 exhibits strong magnetoelectric coupling. For a symmetry-consistent theoretical description of this multiferroic phase, precise knowledge of its crystal structure is a prerequisite. Here we report the results of single-crystal neutron diffraction on C…
Glass and coir fiber hybrid composites were characterized for the addition of 0.1, 0.5, and 1 wt% functionalized fCNFs produced from waste coal fly‐ash and were used also as secondary reinforcements for producing both glass and coir fiber composites. Before choosing the hybrid composites fabrication parameters, an opt…
The presence of microorganisms influences corrosion of metallic materials by either an accelerating or an inhibiting effect. While most studies have focused on corrosion influenced by bacteria, especially sulphate-reducing bacteria, fungus (or mould) is another form of microorganisms which can significantly affect cor…
Abstract In this work, cadmium sulfide (CdS) nanoparticles were synthesized from a new Cd-octanoate complex via a simple thermal decompose method. The crystallinity of the product was obtained from X-ray diffraction (XRD) pattern. The morphology and product size were analyzed via scanning electron microscopy (SEM) and…
Blends of polyamide 12 and small amounts (0.15–1 wt%) of the excimer‐forming fluorescent dye 1,4‐bis(α‐cyano‐4‐octadecyloxystyryl)‐2,5‐dimethoxybenzene (C18‐RG) are produced by melt‐processing. While green monomer fluorescence from well‐individualized chromophores is observed at low dye concentration (0.15%), higher d…
Cationic modulation of the dominantly negative electrostatic structure of phospholipids plays an important role in bacterial response to changes in the environment. In addition to zwitterionic phosphatidylethanolamine, Gram-positive bacteria are also abundant in positively charged lysyl-phosphatidylglycerol. Increased…
Electrostatic interactions between thin films of two different ferroelectric materials lead to a layer of free charges localized at the interface between ferroelectrics according to a computational analysis presented in this work. The free charges at the interface between $\mathrm{BaTi}{\mathrm{O}}_{3}$ and $\mathrm{P…
In this study, different types of poly(ϵ-caprolactone) (PCL)-based matrices were prepared by hot-melt extrusion. Methylene blue (MB) was used as a model drug, and various amounts and types of hydrophilic components (polyethylene glycol, PEG or polyethylene oxide, PEO) were added to the extrudates as release rate modif…
Abstract Nanosized GdVO 4 powders were synthesized via a sol–gel method using different carboxylic acids as chelating agent, followed by calcination at 600 °C for 3 h. The effect of different carboxylic acids such as citric acid, malic acid, and tartaric acid on the characteristics of the nanosized GdVO 4 powders was…
The challenge of creating a graphene spin field effect transistor (spin-FET) demands a magnetic gate dielectric material whose magnetization can be switched electrically. We have grown films of Cr2O3 on top of graphite and graphene by pulsed laser deposition that shows this crucial functionality. We demonstrate that t…
Lanthanoid complexes of a tetra-amide substituted calix[4]arene in the cone conformation are characterised by single crystal X-ray structure determination. The structural analysis shows that the metal ions are coordinated to the calixarene through the eight O donor atoms, along with one aqua ligand which is located wi…
Nowadays, the microscopic mechanism controlling the distribution of local glass transition temperatures (Tgs) across thin polymer films is still unclear and thus large‐scale applications of polymer films are restricted. Dynamic Monte Carlo simulations are performed to investigate the key factors dominating the distrib…
Abstract The formation of orthorhombic‐phase GdF3 nanocrystals (thermodynamically controlled product) requires higher activation energy than that necessary for the formation of hexagonal‐phase GdF3 nanocrystals (kinetically controlled product). As a result, whenever a reaction is carried out at higher temperatures, fo…
Abstract In this work silver nanoparticles (AgNPs) have been prepared from silver nitrate (AgNO3) precursor using a green synthesis method at room temperature. Starch with its abundance of hydroxyl groups and its biocompatibility was used as a capping and reducing agent. The formation of AgNPs was confirmed by absorpt…
The use of a simple two-center model to describe exchange-coupled systems of various complexities is common in the field of coordination chemistry and molecular magnetism. In this work we investigate the applicability of this model experimentally, employing multifrequency, single-crystal EPR on axial dinuclear chromiu…
A novel solid-phase method has been proposed to prepare a nanosilica-supported antioxidant by the reaction of nanosilica with 2-mercaptobenzimidazole (MB) and silane coupling agent γ-chloropropyltriethoxysilane. Fourier transform-infrared spectroscopy and other characterization methods confirmed that MB was chemically…
